Executive Summary
This article announces a new security capability focused on shadow data detection within cloud environments. The primary objective is to assist organizations in identifying stale, duplicated, and inefficient data stored across their cloud infrastructure. By highlighting these data inefficiencies, the solution aims to reduce overall storage spending while simultaneously minimizing the organization's exposure surface to potential risks. Although no specific threat actors or malware families are identified in this text, the underlying risk pertains to data exposure and cloud misconfiguration. The recommended mitigation involves deploying detection mechanisms to locate and action upon unused data assets. This approach supports broader cloud security posture management efforts by ensuring that only necessary data is retained, thereby lowering the attack surface available to potential adversaries seeking to exploit forgotten or unmanaged cloud storage resources for data exfiltration or leakage purposes.
Summary
Identify stale, duplicated, and inefficient data — and take action to shrink both your storage spend and exposure surface.
